Patent DE-2502081-A1 (DE)
Title: Cross-linked acrylate application - uses watery dispersion with pigments for fabrics or plastics or glass
Inventor: BERGMANN GERHARD
IPC: D06P1/52
Filed: 1975-01-20
Abstract: A process is claimed for the application of cross-linked acrylate by using a dispersion in water to give an insoluble and fast film on fabrics, plastics and glass. The process eliminates the conventional thermal fixing stage to bond the synthetic resin to fibres. A typical dispersion is 400-900g Erusol 2313 (RTM), and 5-40g of a watery dye paste with water added to make a total of 1000g. The viscosity can be modified by using additives, the dyestuff being not only dye pigments but also metallic or white pigments. The material can be used for dyeing tenting fabrics, and can be used with hydrophobic additives and/or not resisting additives, the acrylate film reinforcing the fabric and preventing fibre deterioration from the sun's rays. In treating plastics such as Plexiglas (RTM), the acrylate film contains pigments which control the transmission of thermal rays in the ultraviolet and visible bands of the spectrum from passing through. The material can be used by amateurs and children for painting materials such as textiles, plastics, glass, wood, ceramics and other materials without risk as there are no toxic components present. The dispersion, without pigments, can be used to stiffen fabrics for lining collars, to stiffen pile fabrics and curtainings. The material can also be used to finish fabrics to give a wash-resistant starched effect.

Title: Butt joint for polyvinyl chloride bands esp. water bars - is formed by welding on additional material esp. preformed strips
Inventor: HOHAUS HEINZ
IPC: B29C65/50
Filed: 1975-04-21
Abstract: A method of welding together butt-joined strips, panels, bands of plastics, esp. for hot-welding of PVC consists of bringing the edges of the bands together but leaving a small gap between, and then applying a hot layer of PVC along the joint so as to cover all three surfaces of each band in the region of the joint, so that they are firmly embedded in the joint material. The joint material may either be extruded continuously or applied as a strip which is welded onto the faces of the bands and penetrates into the gap between them. Where strip material is used, the upper and lower faces of the joint may be formed either simultaneously or consecutively. Used in particular for joining the ends of water-bars in concrete structures, including the forming of complicated T - or cross-shaped joints. The method produces as better and more reliable joint than the fusing together of the material of the bands themselves.

Patent DE-2613207-A1 (DE)
Title: Tungsten incandescent lamp filament - coated for optimum visible light emission with selectively radiant material
Inventor: PROELSS HANS
IPC: H01K1/10
Filed: 1976-03-27
Abstract: The pref. coating materials are oxides of rare earth elements such as a mixt. of thorium oxide and ceric oxide. The frequency band width of the selective radiator lies exclusively in the visible range and is much narrower than that of a black body radiator such as a conventional uncoated tungsten filament. The new filament is insensitive to chemical reactions with air so that no vacuum or gas filling need be applied inside the bulb. The selectively radian material is applied by an electrolytic process to the finish drawn and wound filament. This produces the desirable fine grain structure. Particularly fine-grained coatings can be produced by vapour deposition processes as used in cathode sputtering.

Title: Linearisation device for gas analyser - using infrared calorimetric analysis of exhaust gases has operational amplifier characteristic generator
Inventor: VOROSS ZOLTAN
IPC: G01D3/02
Filed: 1976-08-13
Abstract: A linearising device for a gas analyser producing non-linear signals representing composition or concentration of gases is particularly applicable to analysis of vehicle exhaust gases containing carbon monoxide and hydrocarbons. Such analysis employs infra-red calorimetry techniques, whereby the direct display of signals produces upper scale compression and lower scale region expansion. A series of operational amplifiers is connected each with one input supplied with the input signal. Each amplifier has its other input supplied with an offset voltage, and each has a fixed gain. The first amplifier has a zero offset voltage. The amplifier outpus are connected via diodes to a common output point. The circuit constitutes a function generator of opposite characteristic to non-linear relation to be compensated.
